Evaluation of Seismic Behavior Due to Vertical Irregularities in High Rise Reinforced Concrete Buildings
This study investigated the behavior of high-rise reinforced concrete structures with vertical irregularities caused by seismic loading. The ability of the building to endure all of the load during operation should be considered in design process. The irregularities in the building cause to impair stiffness and performance of the structure, particularly during the earthquake. Therefore, it is necessary to evaluate the effects of vertical irregularities on building, especially high-rise buildings. This study employs an S-Shaped structure with five vertical irregularities. Numerical analysis was used by using STEDA 3D software. The dynamic load used is based on time history data from the previous earthquakes, including the El-Centro, Kobe, and Parkfield. The seismic behavior evaluated in this study consist of shear force, lateral deformation, structural stiffness, the relationship between base shear and top displacement, drift ratio, maximum acceleration response, capacity curve, and top orbit of the building. Based on the numerical analysis results, it can be concluded that each model has a different seismic performance even though it is given the same earthquake load and material properties. The vertical irregularity of the building greatly affects the behavior of the structure due to seismic analysis.
